METHOD 4OF REMOVABLY APPLYING END CLOSURESITO VESSELS.

To. all whom *it may concern:

Be it known that I, GEORGE W. BEADLE, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Methods of Removabl Applyin End Closures to Vessels; and I do hereby eclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the lart to which it appertains to make and use the same.

' fIhe present invention relates to a method of removably applying end closures to car` tons, particularly to those of the type disclosedin my co-pending application Ser. No. 611,451 dated February 28, 1911 wherein theclosure consists of a dishedv disk having a securing flange and an outlying apron; and has for its purpose amanner of applying -such closures to vessels and securely lockingr the same by forming complementary interlocking elements on the carton rim and closure flange respectively,`and ironing the apron against the cartons outer surface, all in one continuous operation, and all to the end that a tighter locking joint and more effective` liquid seal is obtained than heretofore; also to keep the pouring rim of the vessel in its sterilized condition, and wherein the closure may not be removed and replaced without showing evidences thereof.

The manner of making t-he closures and I the various stages in the operation for appl ing the same is described in detail in the o lowing specification, and the necessaryv apparatus for carrying the same into effect is disclosed in the accompanying drawings wherein Figure 1 is a central vertical sectional view through the dies for forming the closure. Fig. 2 is a central sectional view of the closure applied to the carton showing the spinner as forming t-he initial interlocking therebetween. Fig. 3 is a similar view showing the'completion of this operation. Fig. 4 1s aview of the carton and closure, partly in section, to show the interlocking joint. Fig. 5 is an enlarged detail section of Fig. 4, and; Fig. 6 is an enlarged detail section illustrating themanner of removing the closure.

lThe closures are made by the apparatus disclosed in Fig. 1, consisting of an upper Specioation of Letters Patent. Application ined February as, 1911. serial Ne. 611,449;

or female 'die 1 having an annular and Adownwardly disposed lip or rim 2, and a central and downwardly disposed plate 4or head 3, which plate is removably secured to the die l by a plurality of screws 4. The projecting portion of the head 3 provides with the rim 2 an annular groove or'ohannel which is of substantially inverted U- shaped design and is adapted to receive the annular edge 5 carried by the lower or male die 6. In operation the die head 3 coperatin with the recess, provided by the vedge 5, dishes the inserted disk 8'; and said edge 5 cooperating with its res ective elements on the female die'forms on t e disk its inner or locking 'flange 9, the outlying apron 10, and the rim `11 formed at 'the juncture .of said flange and apron. Y l

In applying the closure to the carton said closure, when in the form shown in Fig. 1, is loosely fitted over` and infoldsl the open end wall 12 of the carton 13, and by the means of a die 14 the closure is locked to said carton wall by a spinning operation.

` The spinning die 14 is provided with a channel 15 having a relatively abrupt inner curved surface 16 and a gradual and outwardly disposed surface 17. In the initial spinning operation the surface 17 curls or turns inwardlythe flange 9 and apron 10 infolding the rim 12 into substantially that position shown in Fig. 2. This operation partially crimps the surrounding edge 8a of the dished portion 8. In the further spinning operation the surface 16 is brought into coperation with the surface 17 and forms on the edge of the pouring rim 12 a bead 18 and on the closure rim a complementary bead 19 inclosing and interlocking therewith. This operation also finally effects the'crimping of the edge 8 binding the same against the inner carton surface 12. During the foregoing operation it may, in some instances, be deslrable to iron the apron 10 against the carton surface and to ythis end it is proposed to equip the spinning tool 14 with any suitable ironing device as illustrated diagrammatically at 2O in Fig. 3. By thus interlocking the removable flexible closure of the carton the following advantages are obtained, viz A more secure and liquid tight joint is effected than heretofore; the pouring edge of the carton is maintained in its sterilized condition; the apron may be iexed for the ready removal of the closure as indicated in dotted lines in Fig.

5 and in full lines in Fig. 6. Further in thus removing this closure of flexible naaterial a cup is made which catches the dirt; and the closure can not be removed or replaced Withoutevidences thereof, since the flexing of the apron breaks or cracks the outer surfacel thereof.

It is evident that those skilled in the art Amay vary the details of the steps disclosed Without departing from the spirit of the invention, and therefore I do not wish to be limited to such features except as may be 4required by the claims. y

' What I claim is L 'Ihe` method of removably applying i locking closures to vessels which consists 1n closing the vessel with a dished disk of flexible material having a protruding rim of double thickness; vand curling the edge of.

said rim by means of a spinning operation and thereby forming a bead onthe mar inal edge 0f the vessel, While leaving an out ying apron and producing a hollow interlocking bead on the 'closure at the edge of the rim, substantiallyv asl described.

2. The v'method of removably applying Y locking closures to paper'vessels which consists in closing the vessel with a paper disk. and infolding the wall of the vessel and lmarginal edge thereof with a rim of doublev inwardly said rlm by means of a spinning operation to form interlocking beaded portions on the cartons marginal edge and the rim edge of the closure respectively, and forming on the dished portion of the disk an oppositely disposed bead contacting with the interior surface of the carton, substantially as described. y

4. The method of removably applying locking closures to cartons which consists Copies of this patent may be obtained for ve cents each, by addressing Washington, D. C.

in closing the vessel with a dished paper disk and leaving a protruding run lnfolding the end of the carton Wall, and an apron disposed against and extending longitudinally of the cartons exterior surface; 'turning inwardly said infolding rim by means of a spinning operation to form a bead on the marginal edge of the carton and a complementary interlocking bead on the edge of said infolding rim; and in the same oper-y ation forming on the dished disk portion an oppositely disposed bead contacting with the cartons interior surface, and ironing the apron against the carton, substantially as described.

5. The method of ,removably applying locking in closlng the vessel with a paper disk having a dished portion fitting within the carton and an infolding rim overlying a por' tion of the cartons inner surface and a relatively greater portion of the cartons outer surface; turning said rim inwardly by spin'- ning"I to form a bead' on the marginal edge of the carton and a complementary interlocking bead on the edge of said infolding rim, and in the same operation forming on the dished disk portion an oppositely disposed belad contacting with the interior surface of the carton, and ironing the outer infolding rim portlon against the exterior carton surface, substantially as described. v

6. The method of removably applying locking closures to cartons which consists in closing the vessel with a paper disk having a dished portion closely fitting Within the carton, and having a protrudlng rim closures to cartons which conslsts closed by infolding the open end of the cartons Wall; turning said rim inwardly by spinning to form -a bead on the marginal edge of the carton and a complementary interlocking bead on the edge of the infolding rim, and by and duringthe same operation formin around the dished portion an oppositely isposed bead contacting with the interior surface of the carton -immedi ately beneath said interlocking beads, sub'- stantially as described.
